Positive electrode, method of producing the same and lithium battery using the same |
摘要 |
<p>The present invention provides a positive electrode, which contains at least one organic sulfide compound selected from the group consisting of a thiolato compound and a thiol compound, and at least one selected from the group consisting of sulfur and a lithium sulfide represented by Formula (1): (LixS)n, where 0<x≤2 and n>0, a method of manufacturing the positive electrode, and a lithium battery using the positive electrode. Compared with the prior art lithium battery, the lithium battery using the positive electrode of the present invention has a greater capacity and a higher voltage. The positive electrode of the present invention effectively suppresses escape of the positive electrode active material from the positive electrode during charge and discharge operations and thus actualizes a secondary battery of high energy density having a less decrease in service capacity. <IMAGE></p> |
